Definitions

  • the invention relates to a sheet metal dowel which, according to the preamble of claim 1, comprises the following parts: a threaded sleeve for screwing in a screw, two semi-cylindrical shaft shells which can be expanded outwards by axially acting tensile forces , which are integrally formed on the edge of the threaded sleeve and diametrically opposite the free ends of the shank are brought together to form a shank neck, and tabs angled radially outward from this shank neck for engaging the dowel at the edge of a dowel hole.
  • Such a sheet metal dowel is known for example from GB 21 91 838 .
  • the two shaft shells have several kinks along their length, one kink on the threaded sleeve and one on the threaded neck and another approximately in the middle.
  • the shaft halves on the shaft neck and below the threaded sleeve bend outwards, while the shaft halves fold inwards at the middle kink.
  • the two lower shaft halves are supported on the back of the carrier plate.
  • the object of the invention is therefore to so the aforementioned sheet metal dowel design that the shaft can be used universally in any building material and thereby at the same time a stable support of the threaded sleeve on the spread shaft is guaranteed.
  • This object is achieved in that a plurality of helically wound webs is cut out of the shells , which extend over the entire shell width to the remaining edge strips and also spread sideways when the screw is screwed in.
  • This anchor is certainly not suitable for anchoring in hollow blocks or carrier plates, since the coiled webs according to Figure 6 of the patent drawing are of such a width that the spreading and deformation achievable with the easily deformable shaft webs of the subject of the application by the axially acting tensile forces are not provided and also is inconceivable.
  • the shaft shells offer the Tightening the screw provides an excellent hold in the dowel hole of the Carrier stone, regardless of whether it is a solid stone or a hollow stone acts or whether the dowel should be fixed in the hole of a plate.
  • the sheet metal dowel shown in the figures comprises a threaded sleeve 1 for screwing in a metal screw, a compressible shaft 2 with spreadable webs 3 and a shaft neck 4 on the opposite shaft end with radially angled tabs 5 for contacting the dowel at the edge of a dowel hole.
  • the shaft 2 itself consists of two semi-cylindrical shaft shells 6 , which are formed diametrically opposite on the edge of the threaded sleeve 1 by - as can be seen in FIG. 4 - on both sides of the round plate 1 ' pre-punched to form the threaded sleeve 1 in a row from a sheet metal strip formed and then brought together at the free shaft ends - as shown in Figure 2 - in the direction of arrows " Z ".
  • the webs 3 extend over the entire width of the shaft shells 6 to the remaining narrow edge strips 16 and are preferably punched obliquely to the longitudinal axis in said sheet metal strip, so that they are helically coiled in the semi-cylindrical, merged shaft shells 6 .
  • the shaft shells 6 are preferably connected to the edge of the threaded sleeve 1 via two webs 7 which are oriented radially to the sleeve plate 1 ' .
  • FIG. 5 shows the sheet metal dowel according to the invention in use.
  • the dowel sits here with its shaft neck 4 in the hole of a support plate 13 on which another plate 14 is fastened by means of a screw 15 .
  • the threaded sleeve 1 is pulled by the screw 15 to the plate 13 and has the shaft shells 6 spread sideways, whereby a firm rear contact is achieved by the easily deformable coiled webs 3 . It goes without saying that the shaft shells 6, even with transverse or lattice-shaped shaft webs 3, are well able to cover a wide area when they are contracted on the back of the carrier plate 13 .
